The most typical failure for our wells occurred due to rod parted, tubing wear and downhole pump efficiency reduction. The severity of wear is determined by various factors such as high DLS, high water cut, and sand issue. The wear is especially high for deviated and horizontal wells. Therefore, Rodless ESPCP eliminates all rod failures, resulting in a 30–50% decrease in system failure rates, and allows for pump installations in a high-DLS or horizontal section of the well. The main features for Rodless ESPCP are:  Eliminates restrictions to running PCP and beam pump in wellbores with high DLS  Reduces all PCP/BP failures caused by rod string and tubing wear  Decreases torque and pressure losses in relation to high-viscosity fluid  Reduces torque by 20–60% with the elimination of rod string  Improves overall efficiency  Reduces power consumption by almost 25%  Increases safety without having rod backspin on the surface  Environmentally friendly, it avoids leakage at surface without having a stuffing box  Improved efficiency due to low power loss in the rotor The pump speed ranging widely comparing to conventional PCP, therefore, such system flexibility enables easy adjustment to a broad range of well production rates without replacing the pump. The downhole assembly is effective in high temperatures of up to 300 deg F [150 deg C] and is corrosion resistant with special coating. The main component of this technology are: 1-PC Pump 2-Support Unit to handle partial of the axial load and absorbed the vibration 3-Protector prevent the well fluid from emigrating to the motor and absorb the axial load 4-Downhole motor 5-Downhole gauge
